High velocity PV valve (high speed) for oil tankers are approved for use in crude oil tankers, oil products and hazardous flammable chemicals.
Feature:
- 1. Stable operation, minimizing gasoline vapor loss
- 2. Suitable design, compact, minimum maintenance cycle
- 3. In accordance with the latest IMO /MED requirements for ships carrying flammable vapors – MESG 0.9 & 0.65 mm
- 4. Smooth operation
- 5. High breathing flow
- 6. Diverse applications
- 7. No sudden pressure drop
- 8. No maintenance of internal parts required
- 9. External inspection, cleaning and maintenance are not possible without disassembly.
- 10. Adjustable installation pressure (Need to be tested)
- The rapid breathing valve is designed as a device to prevent the discharge of flames into the cargo container/bunker in the tanker and the reduction of excessive pressure or below the vacuum level of the cargo tank during loading, discharge, ballasting and major changes in heat.
